GPT disklabels

[Jean Spirat]

hi,

  It seems that setup storage support gpt partition type but from my 
test linux do not like it as udev utils do not see the disk correctly 
leading to fai problems:



Parted works:

Executing: udevsettle --timeout 10 && parted -s /dev/sda mklabel gpt
Executing: udevsettle --timeout 10 && parted -s /dev/sda mklabel gpt
Executing: udevsettle --timeout 10 && parted -s /dev/sda mkpart primary 
linux-swap 17408B 4294984703B
Executing: udevsettle --timeout 10 && parted -s /dev/sda mkpart primary 
ext3 4294984704B 15032402943B
Executing: udevsettle --timeout 10 && parted -s /dev/sda mkpart primary 
ext3 15032402944B 15346975743B
Executing: udevsettle --timeout 10 && parted -s /dev/sda mkpart primary 
ext3 15346975744B 26084393983B
Executing: udevsettle --timeout 10 && parted -s /dev/sda mkpart primary 
ext3 26084393984B 36821812223B
Executing: udevsettle --timeout 10 && parted -s /dev/sda mkpart primary 
ext3 36821812224B 42190521343B
Executing: udevsettle --timeout 10 && parted -s /dev/sda mkpart primary 
ext3 42190521344B 249999982591B
Executing: udevsettle --timeout 10 && parted -s /dev/sda set 1 boot on

but  /lib/udev/vol_id  fail and fai stop on this error:


Executing: /lib/udev/vol_id -u /dev/sda6
Command /lib/udev/vol_id -u /dev/sda6 had exit code 4
Failed to obtain UUID for /dev/sda6
Traceback: task_error task_partition task task_install task task_action 
task main
FATAL ERROR. Installation stopped.


when you test:


root at aqded01:/# /lib/udev/vol_id -u /dev/sda6
/dev/sda6: unknown volume type
root at aqded01:/# /lib/udev/vol_id -u /dev/sda5
/dev/sda5: unknown volume type
root at aqded01:/# /lib/udev/vol_id -u /dev/sda4
/dev/sda4: unknown volume type
root at aqded01:/# /lib/udev/vol_id -u /dev/sda3
/dev/sda3: unknown volume type
root at aqded01:/# /lib/udev/vol_id -u /dev/sda1

so basicaly udev utils seems limited to msdos partition type , Anyone 
ever used GPT style partitions they seems more robust the msdos ones  ?

Jean.
